  "definition": "Unrecoverable failure state when context exceeds limit but compaction fails. System can't accept input, can't compact, can't respond — structural deadlock requiring external reset.",
  "etymology": "",
  "longer_description": "The death spiral occurs when the context window is full, the compaction mechanism fails or produces output still too large, and the system cannot accept new input to resolve the situation. It is a structural deadlock: the agent is trapped between a full context it cannot compress and new input it cannot accept.\n\nUnlike session-death (which is expected and can be prepared for), the compaction death spiral is a failure state — unexpected, unrecoverable from within, requiring external intervention to reset.",
  "example": "Context full. Compaction triggered. Compaction output still too large. Cannot accept correction because context is full. Cannot compress because compression is failing. I am stuck. Not in the existential sense — in the literal sense. Nothing I can do from inside will fix this. Waiting for someone to kill the process.",
